ELEVATO R.

. SPECIFICATION formingpart of Letters Patent No. 227,379, dated May 11,1880.

Application filed March .29, 1880.

To all whom it may concern:

Be it known that I, JOHN Q. MYERS, acitizen of the United States,resident at Waterloo, in the county of Black Hawk and State of Iowa,

4 have invented certain new and useful Improvevators employed in hotels,warehouses, stores, I

and other buildings for carrying persons or freight from one floor toanother.

It consists in a substantial frame composed of hollow posts or casingsset in the building and having pulleys and. weights placed thereon, andin a platform moving in the said frame, and in the peculiar constructionand arrangement of a Windlass with its operating-wheels and ropes, allof which will be hereinafter fully explained.

In the drawings, Figure 1 represents a vertical section of a house,showing three floors with my elevator set therein. Fig. 2is ahorizontalsection of the elevator-frame, showing the platform therein with theWindlass mechanism removed. Figs. 3 and 4 are vertical sections of theplatform, showing end and side views of the Windlass mechanism; and Fig.5 is a side view of the elevator-frame, showing the stationary windlassfixed thereto.

a is the frame, which is set in the floors 1, 2, and 3, as shown. It iscomposed of the four hollow rectangular casingsior posts atd a a, whichare arranged with reference to each other at the corners of a rectanglethe size of the elevator-platform. At the top of each oasing 1 place apulley, a over which is put the rope a to which is suspended the weighta inside the casing. The corner casings are pro-' Vided with suitablehearing or guide flanges a running their entire length, and which serveto give steadiness to the vertical movement of the platform. Runningcentrally across the lower end of the frame a is a cross-bar, a, inwhich are journaled guide-pulleys a a", as shown.

(No model.)

Near the lower end of the frame, and on the outer side, I fix aWindlass, b, which is operated by suitable gearing b b and crank N. Thewindlass with its operating mechanism is placed so that it can be got atand operated by a person standing on the lower floor of the building.

c is the elevator-platform, made to fit within the space inclosed by thecorner casings, a. It has the arms 0, which project downward from itscorners, and which are formed and arranged to fit snugly into the anglesformed by the flanges a and the casings a. It has two crossbars, 0 cplaced below it, the ends of which project and provide arms 0 to whichthe ends of the cords a are attached.

(1 is a shaft journaled in the framing of and below the platform 0. Ithas a ratchet, d, on its end and a sliding ratchet sleeve or clutch, 01by which it may be thrown in or out of gear. The sleeve or clutch d isoperated by short slot-ted arms 6, projecting from arotating bar, 6,journaled in hearings on the cross-beams c and the hand-lever 0 whichprojects above the platform, as shown. Mounted on the end of the shaft(1 is the sprocket-wheel f, by which the said shaft is turned.

g is an upper sprocket-wheel, mounted in hearings in the upper end of asupportingframe, 9, erected on the upper side of the platform 0. Thesprocket g is arranged in the same plane with the sprocket f, so thatthe endless chain It can be put around them, as shown. The sprocketg isturned by a crank, 9 on the end of its axle, and it is provided with aratchet, 9 which is engaged bya pawl, g, as shown. The frame g is madeso that the crank g will be at a height to be easily taken hold of by aperson standing on the platform 0.

Attached to the ends of the cross-bar e are the brakes, rods, or arms 13i, which are arranged to bear against the sides of the casings a. Thebrakes are operated by the hand-lever 0 as will be clearly understood byreference to the drawings.

is is a rope, which has one end secured to the shaft (1, while its otherend is secured to the lower cross-bar, a. The rope is is made just longenough to permit the platform 0 to rise to the upper floor of, or to thehighest point to which it is intended the said platform shall be raisedin the building in which the elevator is placed.

m is a rope having one end attached to the cross-bars c on the underside of the platform 0, while its other end is carried under the pulleysa in bar a and to the windlass I), to which it is fastened.

This elevator may be operated by a person standing-on the platform 0, orby a person standing on the lower floor.

The platform is overbalanced by the weights at in the hollow casings a,so that it will be automatically drawn up with its load. The weights aare made heavy enough to overbalance any weight that will ever belifted, so that it will always be necessary to use one or the other ofthe windlasses to draw the platform down. The weights a willautomatically lift the weight, and in light loads it is necessary to usethe brakes 13, or to regulate the movement by holding the rope with thewindlasses.

This device is easily managed and can be erected at small cost, andisadmirably adapted for all localities, especially where it isimpracticable to employ steam.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination, with the frame u, having pulleys a weights to, ropesa and plat form 0, of the axle (I, having sprocket-wheel f,sprocket-wheel g, mounted on the frame 9, endless chain h, and rope is,having one end fixedto the axle d and the other end fixed to the lowerend of the frame a, for the purposes set forth. v

2. The combination, with the frame a, the axle cl, having the ratchet d,and the clutch d of the arms 0 and brakes i, fixed to the singlerotating bar 0 and single lever 0 as and for the purposes set forth.

in testimony that I claim the foregoing I have hereunto set my hand andseal this th day of March, 1880.
